The requested module dayjs.min.js does not provide an export named 'default' #423
Description
TanStack Devtools version
0.10.2
Framework/Library version
react 19.2.5
Describe the bug and the steps to reproduce it
I have an existing project using tanstack router and tanstack query that were using the individual devtools. I followed the steps to add a TanStackDevtools component and ran into two problems:
- A constant loop in vite with this error. I fixed this by adding '@tanstack/devtools' to vite.config.ts optimizeDeps.exclude.

- this runtime error that I have not been able to bypass:
SyntaxError: The requested module '/node_modules/.pnpm/dayjs@1.11.20/node_modules/dayjs/dayjs.min.js?v=559389e5' does not provide an export named 'default' (at tree.js?v=559389e5:6:8)
the line it's pointing to is in @tanstack/devtools-ui/dist/esm/components/tree.js
import dayjs from "/node_modules/.pnpm/dayjs@1.11.20/node_modules/dayjs/dayjs.min.js?v=559389e5";
I think it has to do with the tsconfig option allowSyntheticDefaultImports which I did not previously have set, but I tried adding it (and rerunning with vite dev --force to force it to rebuild) but that did not make it work.
Sorry, I'm going through the trouble of creating a bug report, I don't have the time to also create a minimal reproducible example. Close the issue if you must.

Thanks again for the report. Rephrasing the key triage ask clearly:
To make this actionable, we still need a minimal reproducible example. The current repro link points to the issues list, not a runnable reproduction.
Please share either:
that reproduces this with the same dependency versions (@tanstack/devtools, React, Vite, and package manager), plus exact steps to run it.
Without a debuggable repro, it’s very difficult to reliably confirm and fix the issue.

ok, well, my bad. It seems the second problem was a result of the first, which was the real problem, and was the result of an older solid-js being in package.json (no idea how it got there, as I don't use solid). Taking that out made it all work correctly now.
